Really polished game! The UI and palette are clean, the skippable tutorial teaches place, merge and deliver in just a few steps, and the order system gives every move a clear goal. Merging blocks up and delivering them for coins and a multiplier is very satisfying. One suggestion: the two-tap merge (first tap highlights, second tap merges) was not obvious at first and does nothing when levels differ, so a small hint text there would help. Great work!
